WILLIAM B. WAIT, or NEW roan, N. Y.

MA RGINAL HOLDING DEVICE.

To all QU/ZOWL it may concern:

Be it known that I, WVILLIAM B. farm, a citizen of the United States,residing at New York, county of New York, State of New York, haveinvented new and useful Improvements in Marginal Holding Devices, ofwhich the following is a specification.

This invention relates essentially to devices for engaging the sheetwhile the impressions are being produced and it is adapted to be appliedto the embossing machine shown in the U. S. Patent #900,622, granted tome October 6th 1908.

The invention consists in the novel method of holding the margins of thesheet while it is being fed between the cylinders. The embossing platehas elevations and depressions with raised characters for printingliterature, music, and the like, for reading by the blind, and it isprovided with indentations for holding the margin of the sheet of paperwhile it is being embossed. This indenting device may form an integralportion of the embossing plate or may be separate therefrom and mountedor fixed on the cylinder. The lines of indentations or points are equaland minimum distances apart and are so placed that they hold the paperin advance of the embossing impression. The indentations extendcontinuously along the margin of each plate, and in combination with theimpression cylinder will engage the sheet and prevent it from creep-I-Ieretofore it has been found in printing without this device that thepaper was drawn inward from the margins, thus giving more paper than theprinted surface required, and preventing proper alinement, alsoresulting in rufliing or creasing the sheet of paper toward the end ofthe impressions.

The function of the device is to secure the paper at the margins shortlybefore the embossing begins, and to maintain its hold upon the marginscontinuously throughout the impression. In this instance the deviceprevents the lines impressed upon one side of the leaf from interferingwith the lines embossed on the reverse side of the sheet.

The device has the advantage of greatly reducing the cost of embossedprinting for Specification of Letters Patent.

the blind as it permits the use of lighter and less expensive paperswhich is much to be desired, owing to the great bulk of the paperordinarily used in this kind of printing.

The novel features of the invention are more fully described in thefollowing specification and claims and illustrated in the accompanyingdrawings in which:

Figure 1 represents a diagram of an embossing machine embodying thisinvention. Fig. 2 is a perspective view of an embossing plate. Fig. 3shows a sheet partly embossed. Fig. 4: is a fragmentary view of a sheetshowing bot-h sides embossed.

In this drawing the letter a designates the embossing cylinders and bare the impression cylinders. These cylinders are arranged in pairs andthe embossing cylinders have elevations and depressions on which arefitted correspondingly shaped plates with the embossed characters formedon the plates. The first pair of cylinders emboss one side of a sheet ofpaper (5 while the other pair of cylinders emboss the reverse side ofthe paper. Each impression cylinder 6 has an elastic jacket whereby theembossed characters are produced; the foregoing parts of the machine arewell known.

Each plate is provided with a line or row of indentations 6 best seen inFig. 2, which when the sheet is fed between the cylinders engage themargins of the sheet and prevent it from shifting. These devices 6impress along the margins of the sheet, a row of indentations f, asindicated in Figs. 3 and 4. The indentations on the margins of the sheetdo not represent any meaning in the reading of the sheet. Theseindentations are preferably equal distances apart and are quite closetogether so that all portions of the sheet will be evenly tensioned andheld while the embossed characters are being produced.

I claim:

1. In an embossing machine the combination with a plurality of cylindersof plates carried by the cylindersfor simultaneously embossingcharacters on both sides of a sheet of paper, a series of projectionsforming an integral. portion of the plates for indenting the margins ofthe paper equal distances apart while the impressions are produced.

2. In an embossing machine the combination with a plurality of embossingand impression cylinders, of plates carried by the In testimony whereofI have hereunto set embossing cylinders for embossing characmy hand inthe presence of two subscribing ters on both sides of a sheet of paper,and Witnesses.
